GATE.

Application filed July 15 To all whom it may concern:

Be it known that I, SIMON SOLBERG, a citizen of the United States, residing at Mc- Intosh, in the county of Polk and State of Minnesota, have invented certain new and useful Improvements in Gates; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved gate of the type commonly called farm gates; and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 5 is a detail View in horizontal sec- Fig. 6 is a detail view'in horizontal section taken on the line 6-6 of Fig; 1;

Fig. 7 is a plan view showing the gateclosed by means of full lines and in an open position by means of broken lines; and

Fig. 8 is a perspective view of the wheel tripping device.

The numerals 9 and 10 indicate, respectively, front and rear gate posts located on opposite sides of a roadway, the latter of which is considerably higher than the former and is held upright by an anchor rod 11 to offset the weight of the gate. The gate, as shown, comprises a rectangular tubular frame 12 suitably braced by front and rear oblique bars 13, and a woven'panel 14 secured thereto. Said gate is supported from the gate post 10 by upper and lower hinges 15 and 16, respectively, for double swinging movement. The upper hinge 15 is Specification of Letters IIatent. f Patented Feb. 10, 1920.

in the form of a loose vertical pivot and the lower hinge-16 comprises a pair of laterally spaced vertlcal pivot rods anchored to said post and a pair of coiiperating fulcrum lugs anchored to the lower member of the gate frame 12. The action of the lower gate hinge 16 is such as to gravity center the gate. A longitudinally adjustable rod 17 supports the front end of the gate from the upper end of the gate post 10 to which it is flexibly anchored by a bracket 18. To the upper and lower members of the gate frame 12.is secured a strut '19 which supports the intermediate portion of the rod 17.

The ate is locked in a closed position by a spring latch 20 and cooperating notched lug 21 bolted to the gate post 9. The latch 20 is cammed into the notch of the lug 21 by engaging the sides thereof when swinging in either direction to a closed position. As shown, the latch 20 is in tlfe form of a spring rod having its lower end anchored at 22 to the front upright member of the gate frame 12. The free or upper end of the latch 20 extends throu h slots in a plurality of vertically spaced brackets 23 clamped to the front upright member of the gate frame 12-.

On each side of the gate, is a vehicle striking or buffer late 24, the upper end of which is secure by a hinge 25 to the respective side of a thrust tie bracket 26 for swinging movement transversely of the gate. The bracket 26 is, as shown, in the form of an endless vertically disposed band which completely surrounds the gate frame 12 at its intermediate portion. The sides of the bracket 26 are parallel and rigidly connected by upper and lower tie rods 26 which hold said sides properly spaced. At its upper and lower ends,the bracket 26 is contracted onto the upper and lower members of the gate frame 12 and rigidly secured thereto by rivets.

A plunger 27 as shown in the form of a round rod, is mounted in alined bores in the sides of the bracket 26 for endwise sliding movement transverselyof the gate. On each end of the plunger 27 is an expanded head 28, between which and the respective side of the bracket 26 is compressed a coiled spring 29 that encircles said plunger.

plunger heads 28 and are held spread thereto hold the same open lon ends, extend in opposite directions there from and have their other ends anchored,

the one to therear brace rod 13 and the other to the panel 14:.

Extending transversely through the gate is a lever 31 intermediately pivoted to a bearing bracket 32 on the bracket 26. Each end of the lever 31 is connected to the upper end portion of the latch 20 by a rod 33.

Formed with the lever'31 in an intermediate arm '34 attached at 'its'outer end to the in termediate portion of the plunger 27 by 'a slot and pin connection 3 1. It may be here stated that the connecting. rods 33 have sufficient flexibility to permit one thereof to bend or buckle when the other thereof is moved endwise by the'lever 3]. to release the latch 20. It will also be noted that the lever 31 and its arm 34 afford a double bell crank.

From the 'above'description it is evident that when one of the buffer plates 24. is struck by the bumper Y'of an approaching automobile Z, as shown'in Fig. 2, or any other part thereof, or by the pole ofa vehicle, the inward movement thereof through theconnection 34: will rockthe double bellcrank 3134 and thereby draw one of the and at the same time the other of said rods will be buckled to permit the required releasing movement .of said latch. The inward movementof the bufler plate 24 struck by the vehicle will' compress the respective spring 29 by moving the plunger 27 endwise in the bracket 26, and this movement ofsaid plunger will swing theother of said buffer plates outward and thereby place'the connected springs 30 under strain so that when the latch 20 is released the action of the compressed springs will, together with the momentum of the vehicle, swing the gate away from the-approaching vehicle and into an open position.

As previously stated, the gate is hinged to swing closed under the action of gravity and enough to permit the vehicle to pass t rough the gate opening and beyond the open gate, there is provided on each side of said gate opening a latch 35 arranged to automatically interlock as shown with the lower member of the gate frame 12 near the front end thereof when said gate is swung into an open position. It

is of course understood that the latches'35 may be arranged to ngage any other part of the gate. The two latches 35 are located one on each side'of the gate post 10 and sub-' stantially in alin'ement therewith so as to ermit the gate-to swing approximately 90 egrees on each slde of lts closed-position.

movement of said latch positive. latch 35 is moved into an inoperative posi-' tion by the gate frame 12 when the gate is As each latch 35 is' identical the one with thereunder, will drop under, action of gravity and thereby interlock the said frame to hold the gate open. i

To release the (latch 35 and thereby permit the held gate to swing closed, there isprovided a tripping board 37 which extends transversely across the adjacent wheel track in respect to the'post 36. To the outer end of the tripping board 37 is rigidly secured a yoke-like extension 38 through which the post 36 projects. A tightly coiled spring 39 yieldingly connects the outer end of the latch lever-35 to the transverse'portion of the extension 38. A pair of coiled springs 40 have their upper ends anchored to opposite sides of the post 36 and their lower ends are secured to the side members of the extension 38. These springs 40 are arranged to yieldingly hold the connected end'of the tripping board 37 raised, as shown in Fig. 8. raised by the springs 40, the tightly coiled spring 39 acts as a relatively rigid connection and holds the connected end of the latch When the tripping board 37 is lever 35 raised, thus making the gravity As the swung open, the lifting movement of said latch will force the raised end of the tripping board 37 downward against the tension of the springs 40 through the connection 39. After the gate has been opened by an approaching vehicle, said vehicle, after having passed through the gate, is so guided that its rear wheel nearest the hinged end of the gate will ."pass over the tripping board 37 and lthereby depress the same against the tension of the spring 40 and re-- lease the latch 35 through the spring connection 39. If the downward movement of the tripping board 37 is greater than the latch 35, the spring connection 39 will yield to permit the required movement of the tripping board.

What I claim is 1. The combination with a self closing swinging gate, of a latch on the gate for I tween the striking plate and the latch.

centered plunger, a vehicle striking plate on each end of said plunger, and tripping connections between the plunger and the latch.

3. The combination with a self closing double swinging gate, of a latch on the gate for holding the same closed, a spring centered plunger, a pair of vehicle striking plates having one of their ends hinged to the gate and their other ends spring connected to the ate, a spring centered plunger interposed etween the two "striking plates for holding the same spread, and tripping connections between the plunger and the latch.

4. The combination' with a self closing swinging gate, of a latch for holding the gate open, a Wheel actuated tripping board extending transversely across one of the wheel tracks, yielding means for holding one end of the tripping board raised, and a tripping connection between the latch and raisedend of the tripping board. 7 1

5. The combination with a self closing swinging gate, of a latch for holding the gate open, a wheel actuated tripping board extending transversely across one of the wheel tracks,' yielding means for holding one end of the tripping board raised, and a yielding tripping connection between the latch and raised end of the tripping board.

6. The combination with a self closing swinging gate, of a post, a latch lever. in

termediately pivoted to the post for holding the gate open, a spring anchored to the post and attached to one end of the tripping board for yieldingly holding the same raised, a yielding connection between the latch lever and the raised end of the tripping lever for moving the latch to and from operating position.

In testlmony whereof I aflix my signature in presence of two witnesses.
